l Claim. (Cl. Ztl-52.4)

This invention relates to weather stripping particularly adapted for double hung windows, and in particular a sheet of material, such as metal, having a U-shaped intermediate section extended over a parting strip of a sash frame with ends extended from the U-shaped section across the surfaces of the sash channels of a window frame.

The purpose of this invention is to provide a liner for the inner sash engaging surfaces of the side rails of a window frame in which means is provided for resiliently holding the sash of a window frame tight, with looseness, vibrations and rattling eliminated, and whereby passage of air between the sash positioned in the frame and the inner surface of the frame is substantially prevented.

Various attempts have been made to combine metal liners with window sash and frames to eliminate wear between the sash and frame and to prevent looseness, rattling, and leakage of air around the sides of the sash, however, such devices require changes in the structure of the window frame and for this reason they are not readily adapted to conventional window frames. this thought in mind this invention contemplates a relatively thin sheet of material formed to extend over the parting strip between the sash channels of a window frame with corrugated sections thereof extended over the base surfaces of the channels and with the corrugated sections positioned to correspond with the upper and lower positions of the sash for resiliently urging the sash against xed members of the frame.

The object of this invention is, therefore, to provide an improved weather strip which not only closes air passages around the sides of sash of window frames, but also eliminates rattling and facilitates raising and lowering the sash in the frame. y

Another object of the invention is to provide a metal liner for window frames that is adapted to be installed in window frames now in use.

A further object of the invention is to provide an improved metal liner for window frames which prevents looseness, facilitates raising and lowering the sash and substantially seals air passages around the sides of sash positioned in frames, and in which the liner is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies an elongated strip of material having corrugated side sections extended from a channel shaped center section with resilient flanges at the sides of said channel shaped sections, and in which the corrugated sections extend from a point intermediate of the height of the window frame to the upper end of the frame in one side to correspond with the upper sash and from said point to the lower end of the frame on the opposite side to correspond with the lower sash.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure l is a detail showing a corner of a window with frame with a lower sash indicated therein in broken lines and showing the liner of this invention extended over the parting strip and covering base sections of sash channels of the frame.

Figure 2 is a detail showing a similar portion of a window frame, illustrating the upper part of the frame wherein a side flange extended from a channel shaped section of the liner is corrugated to correspond with an `upper sash of the window frame.

Figure 3 is a sectional plan through a window frame taken on line 3 3 of Figure l.

Figure 4 is a similar section taken on line 4-4 of Figure 2.

Figure 5 is a detail showing an elevational view at a point substantially midway of the height of a window frame illustrating the corrugated flanges of the liner with one ange of the channel shaped section corrugated from a point midway of the height of the frame to the upper end and with the other iiange corrugated from the point midway of the height of the frame to the lower end.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved liner which provides a metal weather strip and which is of one piece construction includes a channel shaped intermediate section having a back or web 10 with a section 11 on one side and a section 12 on the opposite side, and with the material extended from the edges of the sections providing flanges 13 and 14 which are positioned to nest against the inner surfaces 15 and 16 of sash openings or channels, as indicated by the numerals 17 and 18, respectively.

The lower portion of the section 11 on one side of the channel shaped section of the liner is provided with an arcuate spring section 19 which extends from a point 2i) to the lower end of the liner and the section 12 on the opposite side of the channel shaped section is provided with a similar spring section 21 that extends from a point 22 to the upper end of the liner or window frame.

The lower section of the flange 13 in the sash channel 17 is corrugated from the point 20 to the lower end of the liner, and the ange 14 in the channel 18 is corrugated from a point 22 to the upper end of the liner or window frame.

' The liner is provided with openings for screws or other fasteners as indicated by the numeral 23.

With the parts formed in this manner the liners are positioned in the sides of a window frame with the channel shaped intermediate section over a parting strip as indicated by the numeral 24 and with the ianges 15 and 16 extended from the edges of the channel shaped section to the trim 25 at one side and to a bead 26 at the opposite side. The window frame is formed with a base 27, and side rails 28 and 29 and the upper ends of the rails are connected with a top or cross rail in the usual manner.

The corrugations in the lower section of the ange 13 of the liner hold a lower sash, as indicated by the broken lines 30, against the rail at the opposite side of the window frame and the corrugations in the flange 14 also hold the upper sash against the inner surface of the opposite side of the window frame.

With the parts formed in this manner continuously metal tracks are provided for the window sash and the corrugations provide means for resiliently holding the sash against vibrations and seal areas between side rails of window sash and side members of a frame in which the sash are positioned.

By this means a weather stripped parting bead and metal jamb liner are stamped from one piece of metal.

The anged and corrugated liner makes window sash weather tight when the windows are closed. It is not 3 necessary for the liner to extend the full length of the parting bead and frame.

The corrugations resiliently hold both sash and facilitate sliding the sash upwardly and downwardly.

The spring arcuate or oval shaped sections resiliently hold the sash against the trim andv beads on the` edges of the side rails of the window frame.

It will be understood that modifications, within the scope of the appended claim, may bemade in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

In a Window frame, a base providing a sill'with side rails extended upwardly from said sill, said side rails having a parting strip positionedv substantially midway of theY width thereof, a bead on the-outer edge, and a trimming strip on the inner edge, thereby providing` sash traveling channels on opposite sides of said 'parting strip, and a one piece metal liner having a channel shaped section midway of the width thereof extendedl around said parting strip and having anges extended from the edges of said channel shaped section, across said sash traveling channels, the anges on each side of said liner lying in the same plane said channel shaped' section having side webs with arcuate spring` sections therein and the flange at one side of the liner being corrugated horizontally from a point substantially midway of the height thereof to the window sill and with the ange on the opposite side having horizontally disposed corrugations extended from a point substantially midway of the height of the frame to the upper end of the frame whereby the corrugations on one side are positioned to coact with the lower sash and corrugations on the opposite side are positioned to coact with the upper sash, said side webs being arranged in spaced parallel relation with respect to each other, said spring sections extending the same distances as the adjacent corrugations.
